In the course of research, experiments were conducted to study and describe the biological and economic features of Allium oschaninii O. Fedtsch. and Allium pskemense B. Fedtsch. in the Moscow region. The object of the research was samples of various ecological and geographical origin, obtained from various scientific institutions in Russia and other countries. The landing scheme was 70x30 cm. The area of the registered plot was 5 m2. Repeatability 4 times. Samples of Allium oschaninii O. Fedtsch. II years of life provided an average yield of green feathers at a level (2.85-3.86 kg/m2), and Allium pskemense B. Fedtsch. (2.593.20 kg/m2). Maximum yields were provided by samples No. 3 and No. 6 of Allium oschaninii O. Fedtsch. and samples No.3 and No.5 of Allium pskemense B. Fedtsch.. Correlation analysis showed that high productivity of the green feather is formed, first of all, due to the number of false stems (r = 0.909). Significant influence is exerted by such features as the number of leaves (r = 0.633), leaf length (r = 0.630), and the length of the false stem (r = 0.604). The nutritional value of Allium oschaninii O. Fedtsch. and Allium pskemense B. Fedtsch. is due to the presence of ascorbic acid (19.2-32.6 mg%), carotene (14.9-26.1 mg%) and biologically active substances, including flavonoids (251-325 mg% ), hydroxycinnamic acids, (155-194 mg%). The content of dry substances in the samples of the two onions studied was 10.3-12.7%, sugars 2.8-4.2%. The nitrate content did not exceed 170 mg%.
